.To (tZZ whom it may concern:

. Be it known that If, JAMES D. HUMPHREY, a citizen of the United States, residing at To- Wanda, in the county of Bradford and State of Pennsylvania, have invented certain new.

and useful improvements in Numbering and Stamping Machines, of which the following is a specification.

My invention has relation to a power numbering and stamping machine; and in such connection it relates more particularly to the construction and arrangement of the same.

The principal objects of my invention are, first, to provide a balanced type-head re quiring little power for its pro er operation and to render it readily interchangeable by the manner of its support and its connection with a driving mechanism; second, to. so arrange the driving mechanism for the typehead asto impart to .the same movements of varying lengths to bring the type-head alternately into engagement with an inkingpad and then into engagement with an article which is to be numbered, stamped, or marked third, to provide the driving mechanism with means to impart a reciprooatory movement to the inking-pad to shift the same alternately into and out of the path of the type-head; fourth, to provide an adjustable inking-pad holder and to adapt the same for the rece tion of inking-pads of varying sizes, and, fi' th, to provide ayielding and adjustable table upon which the article to be marked is placed.

The nature, scope, and characteristic features of my invention will be more fully understood 'froin the following description, taken in connection with the accompanying drawings, forming part hereof, in which-- Figure 1 is atop or plan View of the machine, illustrating the type-head, the manner of balancing and supporting the same, the driving mechanism therefor, and the means controlled by the driving mechanism for shiftin an inkin pad into and out of the path 0' the typeead embodying main features of my invention. Fig. 2 is a side elevational view of the machine, partly in section, illustrating the manner of connecting the inking-pad holder with the machine, the means for adapting the same to inking-pads of varying sizes, the actuatin mechanism for the inking-pad holder, and t e adjustable and yielding table. Fig. 3 is a "front elevational view illustrating the left-hand end of the machine shown in Fig. 1. Fig. 4 is a detail view illustrating in side elevation the means for imparting an oscillatory movement to the type-head, and Fig. 5 is a detail view illustrating, partly in section and partly in elevation, means for adj ustably supporting the inking-pad in its holder.

Referring to the drawings, a is the bedplate of the machine, which supports a standard or framework a, preferably integral with the bed plate a, as shown in Fig. 2. in bearings c of the framework a is located a shaft I), serving as the support for a type-head c, which, as shown in Figs. 2 and 3, is arranged beyond the framework a and swings clear of the same. The type-head c in the present instance consists of a head 0 proper, having numbering-wheels 0 carried by a shaft or barrel 0 which head is supported by an arm 0 provided with a sleeve 0 through which the end of the shaft l) passes. A screw 1) and washer b prevent the disengagement of the sleeve 0 from the shaft 7), but permits of the free turning of the sleeve 0 and its arm a on the shaft b. The arm 0 is provided with a counterweight c, which by being properly adjusted and clamped. thereon by means of a set-screw c counterbalances the weight of the head 0. By the counterbalancing of the typehead 0 very little power is required to oscillate the same upon its fulcral point or shaft 1), and at the same time the head 0 may be readily removed therefrom by the loosening of the screw 1) to either rearrange the numbering-wheels c, to replace the same by other printing means, or to place another type-head on the shaft b. v

The preferred means for impartin an oscillatory movement to the type-hea c is as follows: As shown in Fig. l, the arm 0 of the 5 type-head c is engaged by rollers d arranged on pins d, carried by a lever d, which lever by means of a roller d engages the cam-groove c of a cam-Wheel e. The lever d is provided with a slot d through which passes a bolt f. This bolt in conjunction with a disk or washer f 0 amps the lever d to a headed bolt f mounted in a bracket 1). The bolt f is provided with an annular groove f engaged by the end of a set-screw f of the bracket b, which permits of a free rotation of the boltf in the same. As shown in Fig. 4;, the cam-groove e of the cam-wheel e is provided with two throws a and c which when the cam-wheel is rotated imparts to the its bearings in the framework a, which relever d, by means of the pins d and rollers (1 an oscillatory movement to the arm of the type-head c. Thethrow of the camgroove 6 swings the type-head 0 into engagement with an inking-pad g and back into its normal position to permit the inking-pad g to be moved out of the path of thetype-head c, after which the second throw e coming into engagement with the roller (1 of the lever d, swings the type-head farther down upon atable h and upon an article placed thereon to imprint an impression onto the same. If the type-head 0 shown is replaced by another of either smaller or larger size or the head is required to vary the length of its oscillatory movements, this can be readily obtained by simply sliding the bracket 6 backward or forward on the shaft b and the bolt 7 in the slot (i of the lever (Z until both the bracket 5 and bolt f have been shifted into proper position, in which the same are held by the tightening of the bolt f and by the set-screw b engaging the shaft 6. The cam-wheel e is carried by a shaft 6, having ceives its rotary movement from a shaft 2' by means of a worm '5 and worm-gear e respectively, mounted on the shafts t and e as shown in Fig. 2. The shaft i, which is pref-- erably carried by a partition-wall a of the framework a and by a bearing a of the bedlate a, is positively driven by a sheaf-wheel a from any suitable source of power. (Not shown.) The inking-pad 9, serving to ink the wheels c of the type-head 0 prior to their engagement with an article placed upon the table h, consists, preferably, of a piece of'felt g or other absorbent material placed in a box 9 As shown in Figs. 1 and 2, the boX g is carried by a holder or bracket 9 which has a ran e of sliding rnovement parallel to the shaft in a groove 0., arranged in the frame- Work a. The box 9 carrying the inkingad g proper, is supported in' the bracket g by adjustingscrews g and is clamped thereto by means of a bar g, the rods g of which slide in eyes 9", arranged on the under side of the bracket 9 and are locked to the same by means of set-screws g as shown in 2. The box g being supported by the adjusting-screws g can be held by the same in va ryin angular positions in the bracket g and can e raised and iowered therein. By this adjustment of the box g the inking-pad 9 thereof can be brought into required position when the extent of movement of the typehead 0 is increased or decreased, due to the adjustment of the fuicral point of the iever d,- as hereinbefore described.

The preferred mechanism for shifting the inking-pad g beiew and away f om the t ehead 0 is as foiiows: To the shaft e of the c m- Wheel e is secured a ca I I provided r twothrow portions k which by 7 1 1*. 3w r a .nrougnt aheinately into engagement I hee adapted pernut of the inking of theprintemcee segment 76 actuates the same and imparts to a shaft k connected therewith, a to-and-fro movement. This movement of the shaft is by means of an arm k and link k is transmitted to the bracket 9 of the inking-pad g, and the same is shifted alternately below and away from the type-head c. When the ink ing-pad g is shifted below the type-head c, the same-is brought into engagement therewith by the throw portion 6? of the camgroove e of the cam-wheel e to ink the numbering-wheels 0 thereof. As soon as the wheels 0 are inked the type-head c is returned to its normal position by means of the cam-groove c, after which the inking-pad is shifted backward into the position shown in Figs. 1 and 2. The throw portion e of the cam-wheel e coming into engagement with the roller of the lever d swings the typehead 0 downward onto the table it and brings the numbering-wheels 0 into engagement with an article placed thereon. As shown in Figs. 2 and 3, the table it consists of a platen h, which is connected with a bracket h by means of bolts it sliding in openings arranged in the bracket 7L2. Surrounding the bolts h and arranged between the platen h" and bracket k are located springs h, which support the platen h and permit the same to yield when the type-head c is brought into engagement with the article placed thereon. In order to permit of aproper imprint of the numbering-wheels 0 when the article placed upon the platen h is other than flat in shape and also to compensate for varying movements of the type-head c, the bracket k suporting the platen h by means of a bolt e 18 pivotally secured to a boss a preferably arranged integral with the bed-plate a.
